Here were the rules.
First cake was eaten and drink was drunken.
Then it was a mad dash to the white roses before the queen came. Hawaiian punch was the perfect paint and spitting, spewing, expectorating, etc. were very effective painting techniques. There was even dubbed the "walker spray" which produced more of a fine mist and some very fine coating.
In the end we were shockingly without any red stains on our wonky outfits (huzzah) and the winners proudly showed off their stretchy body part prizes. (And by "showed off" I mean throwing said body parts at one poor knave with a poster board as a target.)
